1， Curved blade design, utilizes wind resources effectively and obtains a higher power generation.
2， Coreless generator, Horizontal rotation, and aircraft wing design reduce the noise to an unperceivable level in the natural environment.
3，Wind resistance. Horizontal rotation and triangular double fulcrum design make it only bear a small wind pressure even in strong wind.
4，Rotation radius. smaller rotation radius than other types of wind turbines, space is saved while efficiency improved.
5， Effective wind speed range. special control principle expended the wind speed to 2.5 ~ 25m/s, utilizes wind resources effectively, and obtains a higher power generation.
ADVANTAGES OF OFF-GRID SOLAR SYSTEMS
1.NO ACCESS TO THE UTILITY GRID
Off-grid solar systems can be cheaper than extending power lines in certain remote areas.
Consider off-gird if you’re more than 100 yards from the grid. The costs of overhead transmission lines range from $174,000 per mile (for rural construction) to $11,000,000 per mile (for urban construction).
2. BECOME ENERGY SELF-SUFFICIENT
Living off the grid and being self-sufficient feels good. For some people, this feeling is worth more than saving money.
Energy self-sufficiency is also a form of security. Power failures on the utility grid do not affect off-grid wind systems.
On the flip side, batteries can only store a certain amount of energy, and during cloudy times, being connected to the grid is actually where the security is. You should install a backup generator to be prepared for these kinds of situations.
Please note that only 2000W Vertical Wind Turbine could be used with on grid system.
For a grid system, you only need a wind turbine + on-grid inverter+ support tower, very easy to connect and install.
ADVANTAGES OF GRID-TIED SYSTEMS
).Many utility companies are committed to buying electricity from homeowners at the same rate as they sell it themselves.
). Electricity has to be spent in real-time. However, it can be temporarily stored as other forms of energy (e.g. chemical energy in batteries). Energy storage typically comes with significant losses.
).The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity (and more money) goes to waste with conventional battery systems.
). According to EIA data[1], national, annual electricity transmission and distribution losses average about 7% of the electricity that is transmitted in the United States. Lead-acid batteries, which are commonly used with solar panels, are only 80-90% efficient at storing energy, and their performance degrades with time.
).Additional perks of being grid-tied include access to backup power from the utility grid (in case your solar system stop generating electricity for one reason or another). At the same time you help to mitigate the utility company`s peak load. As a result, the efficiency of our electrical system as a whole goes up.
